Drupal 8.x

Hopefully there is a simple way to accomplish this, but I have not been able to figure it out.

For a Drupal 8 installation:

I have a content type of Person that has three fields: Detail Reference, Name and EMail

     Detail Reference is an entity reference to the Detail content type with unlimited values

I have a content type of Detail that has two fields: Person Reference and EMail

     Person Reference is an entity reference to the Person content type limited to one value

I'm trying to install modules with composer but I get this error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - composer/semver 1.5.1 requires php ^5.3.2 || ^7.0 -> your php version (8.0.10) does not satisfy that requirement.
    - drupal/core-recommended 8.9.8 requires composer/semver 1.5.1 -> satisfiable by composer/semver[1.5.1].
    - drupal/core-recommended is locked to version 8.9.8 and an update of this package was not requested.
 

So I got this multi-cardinality field of type `text_long` which always contains 3 entries. Let's call them field_1, field_2 and field_3.

After saving the containing node, all the empty fields are getting stripped from the saved entity when they are empty, this is not what I want.

So whenever someone saves a value into one of the latter fields (let's say field_3) because the field_1 and field_2 are empty, the first 2 will not be saved and on subsequent node edits the values I put into field_3 are being shown in field_1.

What I've tried so far:

I have a D8 site with a few languages with the /en version being the primary site. 

I am having an issue with redirects from an additional domain pointing to the site and redirecting to the correct langauge site.

Lets say the primary domain is domain.com which will land by default at domain.com/en.

I have an additional domain 'domain.se' which I need to redirect to the /se version of the site.

At the moment this is how the redirect is behaving: domain.se > domain.com/en

Hi folks,

I'm looking for a steer on how adding recurring schedules at the hour level can be achieved in Drupal. Is there anything in existence already?

Quick outline - we're aiming to recreate a similar level of control to that found in calendar applications, with one important variation, the ability to set intra-day recurrence down to the hour level, and be able to map that to a daily recurrence over days or weeks. This is part of a digital signage project.
